    黑社會性質組織犯罪曾在我國大陸地區銷聲匿跡，但近年來死灰復燃，並以令人震驚的速度在全國各地發展、蔓延，嚴重威脅人民群眾生命財產安全，嚴重破壞經濟、社會生活秩序。
  2. Numerical simulation by cfd was carried out to understand the hot current behavior in a tunnel with longitudinal ventilation. it becomes clear that fire source modeling is very important because the hot current behavior is strongly affected by the fire source position and is sensitive to methods in the modeling of the fire source. the flame area which has developed from the fire source is an area of chemical reaction caused by combustion. even if grids in the vicinity of the fire source are made fine, it was difficult to simulate the heat generation area with consideration to this chemical reaction through using a method for setting the heat release rate simply on the fire source surface. therefore, we proposed a method adopting the knowledge on flame shape under the longitudinal ventilation and incorporating it into numerical simulation and it showed a good agreement with the experimental results. it was shown through experiments in a tunnel with longitudinal ventilation that the hot current developed toward the tunnel center downwind from the fire source near a wall. the cause was investigated by numerical simulation and it became clear from the results that the spiral air by the fire plume created a vortex in the crevice between the wall and the plume

    運用cfd進行數字模擬，以了解縱向通風隧道內熱煙氣流的特性.通過模擬發現對火源進行模擬非常重要，熱煙氣流特性受火源位置的影響很大，並且對火源模擬方法很敏感.火源生成的火焰區是燃燒引起的化學反應區域.即使火源附近的木垛排列完好，也很難在考慮這些化學反應條件下模擬熱生成區域.建議考慮縱向通風隧道內火焰形狀並對它進行數字模擬.模擬結果與試驗結果非常吻合.試驗證明，在縱向通風隧道內，熱煙氣流從靠近墻體火源處順風向隧道中心蔓延.數字模擬結果發現，火災羽流造成的螺旋上升空氣會在墻體和羽流之間形成一個渦流區

    答：隨著農村經濟的發展，許多農民蓋上了磚瓦房，有的已經是鋼筋混泥土結構，但是，仍然還有不少是耐火等級低的土木建築，而且建築毗連隨意性大，發生火災蔓延快，輕易造成「火燒連營」 。
  5. Underground building with its closed, exits lacked, the people density being large, the flow direction of smoke and the spread direction of fire are consistent in the evacuation routes. fires in the underground building are much danger than over ground building. the hazards of smoke are especially strict in underground building, so smoke control in the underground building has becoming the focus

    地下商業街由於其封閉性強，與地面直接連通的出入口少，內部通道的人流密度大，火勢蔓延的方向和煙氣流動的方向與人員疏散的方向相一致，因此一旦發生火災將產生比地上建築更為嚴重的後果，火災時煙氣危害將更為嚴峻，因此地下商業建築的煙氣控制研究越來越受到人們的關注。
